The new kit1 is larger and has a stainless steel chassis. Looks better than the old one.
And yes...the covers are a MUST.

I'm going to build myself some of those kits in due time.
When I'm done you are welcome to drop by to give them a listen to see if its your cup of tea. Then it will give you a good idea what you getting yourself into if you do decide to invest. The kits are undergoing a lot of change. The preamp kit right now looks like the M2. But in a few months time they will look closer like the M3 (to accomodate more transformers and such). The excellent thing about kits is that you can upgrade it bit by bit rather than buy a whole new unit (OPT, caps, atteunators, etc.)
